Turkish Adaptation Study of the Perceived Devaluation Discrimination Scale.

Objective: The aim of this study is to adapt Perceived Devaluation- Discrimination (PDD) scale for Turkish language and culture.

Method: Participants from clinical and community populations were included in the study. The community sample consisted of 145 healthy individuals from the general community and the clinical sample consisted of 85 individuals with chronic psychiatric disorders. Psychometric properties of the Turkish version of PDD were assessed in the general community and clinical samples. Exploratory factor analysis, confirmatory factor analysis, internal consistency analysis, convergent and discriminant validity analyses were conducted.

Results: As a result of exploratory factor analysis, a two-factor structure for PDD emerged in both the general community and clinical samples. Confirmatory factor analysis also supported the two-factor structure in both samples. These factors were named as Perceived Discrimination and Negative Evaluation and Perceived Acceptance and Non-negative Evaluation subscales. Cronbach's alpha values for PDD were 0.76 in the general community sample and 0.79 in the clinical sample. Alpha values of PDD subscales ranged between 0.72 and 0.77 in both samples. While convergent and discriminant validity tests provided partial support for construct validity of PDD in the general community sample, the convergent validity tests conducted with the clinical sample provided evidence for validity of PDD.

Conclusion: Based on the results of the present study, it has been demonstrated that the Turkish version of PDD is reliable and valid and can be used with community and clinical samples to measure perceived devaluation and discrimination.
